LINAGORA hublin latest (commit 72ead897082403126bf8df9264e70f0a9de247ff) is affected by: Directory Traversal. The impact is: The vulnerability allows an attacker to access any file (with a fixed extension) on the server. The component is: A web-view renderer; details here: https://lgtm.com/projects/g/linagora/hublin/snapshot/af9f1ce253b4ee923ff8da8f9d908d02a8e95b7f/files/backend/webserver/views.js?sort=name&dir=ASC&mode=heatmap&showExcluded=false#xb24eb0101d2aec21:1. The attack vector is: Attacker sends a specially crafted HTTP request.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
